Hi

I have a proc in which my DDname has three datasets concatenated. I want to add one more dataset to this DD name along with the other three. I need to override this in the JCL. Is there anyway by which i need not use the name of all the other three datasets in the jcl(while giving the override)?
i.e by giving only the new dataset's name in the JCL override, can i concatenate it along with other datasets?

Hi Raak,

So u want to over ride a dd stmt. adn concatenate, as u have not given any dd statement let me take the IGYWCL's proc's dd name an explain

//COBOL.SYSLIB DD DSN=dataset1,disp=shr
// DD DSN=dataset2,disp=shr
// DD DSN=dataset3,disp=shr

this is used when u r copy books are in three different dataset's during compilation.


Cheer's,

Thamilzan.

Can you alter the proc? If not, I do not think you can override without replacing all the others.

If you can't alter the proc to create a method that will allow your single DD override, then "I do not think you can override without replacing all the others."

You don't have to code all DD-statements fully. Just the one you want to add or modify. Below an example of addition of a DD-statement.

The proc:

Code:
//MIEP PROC                                                   
//ST EXEC PGM=IEBGENER                                       
//STEPLIB DD DSN=NTSYS.IMSVS.LOADLIB,DISP=SHR                 
//        DD DSN=NASYS.IMSVS.LOADLIB,DISP=SHR                 
//SYSPRINT DD SYSOUT=*                                       
//SYSUT1 DD DUMMY                                             
//SYSUT2 DD DUMMY                                             
//SYSIN  DD DUMMY                                             
// PEND                                                       
//ST1 EXEC MIEP                                               
//ST.STEPLIB DD     <-- existing in proc                                         
//  DD                     <-- existing in proc                                   
//  DD DSN=AESCLM.P02098L.LOAD,DISP=SHR    <-- new library                 


extende:
Code:
2 //MIEP PROC                                           
  //ST EXEC PGM=IEBGENER                                 
  //STEPLIB DD DSN=NTSYS.IMSVS.LOADLIB,DISP=SHR         
  //        DD DSN=NASYS.IMSVS.LOADLIB,DISP=SHR         
  //SYSPRINT DD SYSOUT=*                                 
  //SYSUT1 DD DUMMY                                     
  //SYSUT2 DD DUMMY                                     
  //SYSIN  DD DUMMY                                     
  // PEND                                               
3 //ST1 EXEC MIEP                                       
4 ++MIEP PROC                                           
5 ++ST EXEC PGM=IEBGENER

  +/        DD DSN=NASYS.IMSVS.LOADLIB,DISP=SHR         
8 //  DD DSN=AESCLM.P02098L.LOAD,DISP=SHR               
9 ++SYSPRINT DD SYSOUT=*                                 
0 ++SYSUT1 DD DUMMY                                     
1 ++SYSUT2 DD DUMMY                                     
2 ++SYSIN  DD DUMMY

Ok Bill, below the proof: first 2 files and then one added:
Code:
//MIEP PROC                                           
//ST EXEC PGM=IDCAMS                                   
//SYSPRINT DD SYSOUT=*                                 
//SYSOUT   DD SYSOUT=*                                 
//SYSUT1 DD DSN=$$NL58.FILE-1,DISP=SHR                 
//       DD DSN=$$NL58.FILE-2,DISP=SHR                 
//SYSUT2 DD SYSOUT=*                                   
//SYSIN  DD DSN=$$NL58.PROCINP.IDCAMS,DISP=SHR         
// PEND                                               
//ST1 EXEC MIEP                                       


Result:

Code:
********************************* TOP OF DATA **********************************
 FILE-1

******************************** BOTTOM OF DATA ********************************
                                                                               


File-3 added:
Code:
//MIEP PROC                                                           
//ST EXEC PGM=IDCAMS                                                 
//SYSPRINT DD SYSOUT=*                                               
//SYSOUT   DD SYSOUT=*                                               
//SYSUT1 DD DSN=$$NL58.FILE-1,DISP=SHR                               
//       DD DSN=$$NL58.FILE-2,DISP=SHR                               
//SYSUT2 DD SYSOUT=*                                                 
//SYSIN  DD DSN=$$NL58.PROCINP.IDCAMS,DISP=SHR                       
// PEND                                                               
//ST1 EXEC MIEP                                                       
//ST.SYSUT1 DD                                                       
//       DD                                                           
//       DD DSN=$$NL58.FILE-3,DISP=SHR                               


Result:

In this one file-2 is overwritten by file-3:

Code:
//MIEP PROC                                                           
//ST EXEC PGM=IDCAMS                                                 
//SYSPRINT DD SYSOUT=*                                               
//SYSOUT   DD SYSOUT=*                                               
//SYSUT1 DD DSN=$$NL58.FILE-1,DISP=SHR                               
//       DD DSN=$$NL58.FILE-2,DISP=SHR                               
//SYSUT2 DD SYSOUT=*                                                 
//SYSIN  DD DSN=$$NL58.PROCINP.IDCAMS,DISP=SHR                       
// PEND                                                               
//ST1 EXEC MIEP                                                       
//ST.SYSUT1 DD                                                       
//       DD DSN=$$NL58.FILE-3,DISP=SHR                               


Result:

Code:
********************************* TOP OF DATA **********************************
 FILE-1                                                                         
 FILE-3                                                                         
******************************** BOTTOM OF DATA ********************************

is there any method for that?


Your overwrite will look like this:
Code:

//STEPX.DDname DD
//              DD
//              DD
//              DD DSN=jjjj.rrrr,DISP=SHR
